As someone admittedly anti-Trump but not quite pro-Clinton I think she won. It wasn't The Greatest Debate of All Time or anything, but she exceeded expectations and shouldn't fall in the polls from this or anything. It won't decisively put Trump away but won't gain him anything either. Anyone who thinks this is the end is a straight-up hack.
I agree 100% with this assessment. Trump can still recover by allowing his people to actually prep him next time.
Hillary actually delivered a really killer line:
Yes Donald I did prepare for this debate, and I also prepared to be President.
